Specification of Letters Patent. I Patented Jung 12, 1917,,

Application filed Apri1,29, 1916. Serial No. 94,376.

To all whom it may concern:

Be it known that I, J oHN Iiowmn, a citizen of the United States,residing at Cleve.-

- ber.

land, in the county of Cuyahoga and State ofOhio, have invented certainnew and useful Improvements in Baling-Presses, of

' which the following is a specification.

This invention relates to baling presses of that type'employing aplunger operating in a chamber, the plunger being operated by a crankand toggle.

' Thepress is particularly adapted and intended for baling scrap metalor the like, for which a owerful press is necessary, and ischaracterized by improvements with respect to the means for operatingthe plunger, with respect to the construction of the plunger and balingchamber, and with respect to the means for closing the chamber,

and in other respects as will more fully ap-- indicates a frame at oneend of which is the baling chamber 7. These parts are 'stoutly.constructed and are adapted to rest on a suitable frame, not shown.Thesides-of the baling chamber incline outwardly from the \side walls oftheframe 6'for ashort dis tance, as indicated at 8 and then inclineinwardly or toward each other, as indicated at 9, to the head end of thechamber. A bottom 13 is supported in the baling chair The. plunger.comprises ing hinged tothe head as indicated at 12 sothat they are freeto swing and follow the inclination of the side walls-9,' therebypressing laterally on the material being baled, during the thrustmovement. The

plunger slides on the bottom 13 and is operated by means of a togglecomprising a pair of bars 14 forming one member and another bar 15forming the other member of the toggle. The bars 14 are pivotallyconnectedto the back of the head ,10 as ina head 1o with wings 11 ateach side thereof, said wings be-v dicated at 16, and the bar 15 ispivoted at its outer end to a cross shaft 17 extending between the sidewalls of the frame 6. The toggle joint is formed by a pin 18, which alsoserves to connect the link 19 which is connected by a pin 20 to andbetween a pair of crank wheels 21 mounted on stud shafts 22 which extendthrough boxes 23 in the sides of the frame and are supported at theirouter ends by brackets 24 th give desirable rigidity. i

The crank gear Wheels 21 are driven by pinions 25 on a cross shaft 26which projects at one end beyond the frame and is supported by a'bracket27. This shaft 26 carries a gear 28 driven by a pinion 29 on acrossshaft 30 which carries a gear 31 driven by a pinion 32 on a shaft33 operated by a suitable clutch pulley 34 and belt 35 from any suitablesource of power. The re-- ducing gearing thus provided gives verypowerful pressure.

. The cover for the baling chamber is indicated at 36, and it is shapedto fit the chamber. At its rear" end it is mounted on rock shafts 37supported in bearings 38 on the frame, and it is counterbalanced --bytwo weights 39 connected to the shaft. For holding the cover closedthere is provided a series of hooks 40 mounted upon the cover, andadapted to engage under lugs 41 on the sides of the chamber. These hooksare arranged in pairs, at opposite sides of the chamber, each pair'ofhooks being secured to or projecting from collars 42 which turn oneccentric pins 42 at the ends of the rock shafts 50 mountedin brackets51; on the covers Each collar has an. arm 43 and the arms at each sideofthe-cover are connected by links 44. One arm at one side is extended asindicated at 45 to form a hand lever,

swing all the hooks atonce, to engage or disengage the same with respectto the lugs 41..

For tightening the hooks, after they areengaged, each shaft "50 hasanarm 53,'and

these arms are connected by links 54, and i one end of one shaft isprovided with a hand lever 52. By swinging this lever, the shafts arerocked in thebearings-51 and the .eccen-.

tricity of the pins 42 which carries the wingsbearing' against saidwallsand adapthooks causes said hooks to draw tightly. against the.lugsAl when thecover is closed,

or to relea'se therefrom when thecover is ,to be opened. ,.Thismechanism provides clamping devices which can be easily and quicklyoperated-"for the-intended purpose and which will withstand any amountof pressure that may be exerted against theunder'side of the cover whenthe plunger isin action.

In the'opration of the press, w th the parts as shown in Fig.v 1, thematerial is .placed within the chamber and the plunger" is advanced; By.its advance the material is.

compressedlengthwise, and the wings 11 sliding in contact with theinclined walls 9,

are forced toward each other with "a power- ;ful wedge action untilfinally: they are brought ,to parallel position, against the head end ofthe chamber,1as shown in dotted linesin. Fig. 2, the bale being thuscom-' walls, a I

ed to be swung inwardly when the plunger .is advanced, by theinclination of said'walls,

and means to operate the plunger.

2. In a baling press, the combination of a balingchamber with convergingside walls, a plunger working in said chamber and'comprisinga head andforwardly projecting leaves hinged to the opposite edges of said .headand bearing at their free ends against said walls andadapted to beswunginwardlythereby, and means to operate the plunger.

3. In a baling press, the combination of a" baling chamber, a plungertherein, and

means carried by the plunger and actuated by the advance thereof toapply lateral pressure to material in the chamber.

4. Ina baling press, the combination with a frame and a baling chamberconnected thereto, of a plunger, andopera-ting mechanism connected"thereto and including shafts having bearings infthe sides of the frame,and bearing brackets for" the outer ends of said shafts, spacedfrom thesides of the'frame.

In testimony whereof, I do afii'x my signal ture in presence of 'twowitnesses.
